Abstract: A wind speed meter comprises a housing and a sensor means arranged thereon. he sensor means is heated by a heating coil whereby the temperature of the metal cylinder which constitutes the mass of the sensor means is measured by a resistivity-sensor. After subtraction of the environmental temperature a temperature difference is obtained which depends from the heating effect of the heating coil and the cooling effect from the wind. In view of a constant heating power the cooling effect of the wind which is proportional to its speed may be exactly determined. Further embodiments of the wind meter may comprise a plurality of resistivity sensors around the sensor means, by which the distribution of the temperature around the metal cylinder may be measured, thereby determining the direction of the wind.
